Laing DDC pump noise. Is it broken or is it just air?

post #1 of 3
Thread Starter 
This is my first Laing DDC pump, and I just use this pump for a temporarily loop right now to clean a waterblock, but is going into a new system.

Here is a video of the noise etc. It is quite high, especially compared to my Laing D5

Is this just air cavitation, or do I need to fix the pump?

The ceramic ball and such seemed to be fine when I pulled it apart, does it need lube?

Although it's difficult to judge the comparative volume that's generally what they sound like.

It is hard to explain how loud it is, but it is easily the loudest thing in the room, even several meters away.

It can be compared to being as loud as a normal phone ringing with vibrate on, on a table.

I think I could assume it's 3 times as loud as my D5.

About speaking volume.

EDIT : Could it be because there is different sizes of tubing in the loop, there is some 1/4" or something, and some 1/2"
